Write 9x+3y=18 in slope intercept form, and identify the slope and the y intercept

Question

Slopes intercept

Answer 1

First of all, divide the equation through by 3 => 3x + y = 6

and then subtract 3x from both sides => y= 6 - 3x => y = -3x + 6

This is slope intercept form with slope = -3 and y intercept = 6...the slope is the coefficient of the x term and the y intercept is found when x = 0.

 

P.S. the general form of slope-intercept is y = mx + b
